' Figure ll is a transverse. vertical seetlonal vmwthrough a completed burial vault I In forming containers or burial vaults in. accordance with my 'invention the contaijner is molded or -cast bottom side up within mold walls formed by a hollow core shaped to conform to the interior of the container and an outer mold wall arranged in spaced relation to the core, the core having faclosed top and the outer mold walls being as much higher than the top of the core as the thickness of the .bottom'of the container. In the drawings the refe'rencecharacter A designates the hollow core which is shaped to'con'form' to theinterior off the container and is formed with end plates 1 side plates 2 and atop. plate v3, 5 The end plates 1 and side plates am adapted to be positioned 'edg'ewi'se in avertical plane upon a base 4-, the said plates 1 and Qbeing properly positioned upon thebase'e y mean 'o c1eats 5 seeur d to the ase'ag inst t e outer s d of [Whiblli i 'liilaeed the. pla es 1 and 23 as nearly sho n in* F gur .1 end 3- Th npperiedges .ofthe plates. ram 2. are @0 glebars 6'. ri eted to he insid of the endplates'l and provided at their ends with do nwardly projecting I l l. pins 7 ad pted te'pee th o gh open ngs inthe ends of similar angle. be et. secu to the nsi es offthefsid lpl T anglebar' a de l 'speeed rom the p e ges of th plates 1 and 2 in der to f m for the .top plate 3. which is ara .ithirilf l en eteel end2 as shown in Figu es l nd 3.; ndftheextf einities Of .theengle bar 9 ere'efi e 'de nwardly es at al -nee; e e u e as e. a le.

bars 6 to overlap and rest upon the same with the horizontal flanges of the angle bars 6 and 9 in substantially a common plane. Adjacent their lower edges the end plates 1 are formed with short angle bars 11 which are provided in their horizontal flanges with dowel pins 12 adapted to fit into openings 13 formed in the ends of a longitudinal strap 1% which is secured adjacent its ends to similar transverse straps 15, the said straps 14 and 15 being rigidly secured to the base 1. The side plates 2 are provided adjacent their lower edges with angle bars 16 provided in their horizontal flanges with pins 17 to fit into openings 18 formed-in the ends of the transverse straps 15. The side edges of the end plates 1 are preferably curved asat 19, and are adapted to abut against the ends of the side plates 2, as clearly shown in Figure 2, the said curved portions 19 serving to form curved corners on the interior of the container. lVith the core A'thus assembled it will be seen that it is substantially rigid in construction and is positively held in position upon the baset by the cleats 5 and the l pins 12 and 17 engaging the straps 1st and 15. The outer sides of the side plates 2 are formed with pins 20 projecting laterally therefrom which are-adapted to loosely receive short lengths of pipe 21. r

The outer wall B of the mold comprises ends 21-0 and sides 22 which are adapted to be positioned upon the base 1 in vertical planes and in spaced relation to the core A, as shown in Figures 1 and 2, the lower edges of said ends and sides ofthe outer wall B being arranged within positioning cleats 23 similar to the cleats 5. The upper edges of the ends 21 and sides 22 are connected by angle bars 24; secured to the outer sides of the side walls 22, the ends of which project beyond the ends of said side walls and are formed in their horizontal flanges with pins 25 which are adapted to fit into openings 26 in the ends of similar but reversely arranged angle bars 27 secured to the end walls 210. Theupper edge of the outer wall B project-s upwardly beyond the top plate3 of thecore A a distance equal to the thickness otthe bottom of the container, and the spaces between the ends and sides of the core and outer wall areiequal to the thickness of the walls of the container which it is desired to form. r

In molding a container the core and outer mold wall B are set up on the base 1 as above described and suitable reenforcing material 28 is positioned in the space between the ends and sides of the core and outerwall and above the top plate 3. The plastic material, for instance concrete, is thenipoured into the spaces between the core and outer walls and over the top plate 3 of the core until the plastic material is substantialb flush with the upper edges of the outer wall B. The plastic material is then allowed to set and harden for the necessary period of time after which the mold walls are removed. It will thus be seen that the plastic material in the space between the top plate 3 of the core and the upper edges of the outer wall B forms the bottom. of the container Q, the base t enclosing the top of the container.

In disassembling the mold walls to remove the container therefrom the container and mold walls are inverted, as shown in Figure 4-, and the base 1- is lifted off. This disconnects the straps 14L and 15 from the side plates 2 and end plates 1 of the core. ;The side plates 2 of the core are then pulled inwardly away from the wall of the container, as shown in Figure 4, and lifted vertically out of the container, handles 29 being preferably. provided for so handling the side plates. This removes the angle bars 9 from the pins 7 and the end plates 1 and top 3 can then be removed. The outer wall B is removed by simply raising the end walls 210 thereof vertically to disengage the pins from the angle bars 27, after which the side walls 22 can be removed. In removing the side plates 2 ofthe core A the pins 20 in the sides thereof slip out of the short lengths of pipe 21 leaving the pipewithin the walls of the container, as shown in Figure 4, the said pieces of pipe serving as sockets on the interior of the container of the vault to receive hoisting apparatus for handling the same. v

For molding the cover of the container or vault I utilize a mold D' comprising a base 30 supported on transverse cleats 31 spaced longitudinally thereof, the said base having a core or former plate 32' on the upper side thereof which is formed with a continuous groove 36 spaced inward from the sides and ends of said formerplate. A wall 33 is detachably mounted on said base and surrounds said former plate in spaced relation to theedges thereof to forn'r a peripheral depression 37, and the entire bottom of the mold including the former plate, the groove 36 and the bottom of'the depression 37 is covered with a sheet of metal 320. The wall 33 is of a height equal to the thickness which it is desired to form the cover E of the container, the ends 34: being arched or curved and the inner sides of said wall being concave as at 35. The plastic material is poured into the mold around the projection 32 until the top ofthe material is substantially flush with the upper edges of the wall 33, as shown in Figure 10, the plastic material being rounded at the top to conform to the arched ends 34 to form the cover with a transversely rounded top. The projection flange on the cover E, while the groove 36 forms a rib 38 on the inner side of the cover.

The apparatus above illustrated and described is particularly designed for the molding or casting of burial vaults of concrete, and in Figure 11 I have illustrated the completed vault which may be constructed in accordance with my invention. The cover is adapted to rest upon the edges of the walls of the vault C with the said edges received between the flange and rib 38 on the cover, the said cover being sealed upon the vault in any suitable manner.

lVhile I have shown and described one possible embodiment of my invention,-it will be understood that this is only for illustrating the principles thereof, and that many modifications and changes can be made in the construction and use of the invention without departing from the spirit or scope thereof. Therefore, I do not desire to be understood as limiting myself except as required by the following claims when construed in the light of the prior art.

Having thus described the invention, what I claim is:

1. A. mold including a base, a core comprising side and end plates adapted to be supported edgewise on said base, said plates and said base having cooperating projections and recesses to hold said plates against lateral movement on said base, said plates beingalso formed at one side adjacent their upper edges with cooperating projections and recesses to connect said plates to each other, all of said projections and recesses engaging on edgewise movement of said plates,

and a top plate supported by said second-.

mentioned projections within said side and end plates, and an outer wall member including side and end plates arranged edgewise on said base in spaced relation tosaid core, said plates being provided on their outer sides with cooperating projections and recesses to engage on edgewise movement of said plates and connect said plates to each other.

2. A mold including a base, a core com-- prising side and end plates adapted to be supported edgewise on said base, each of said plates having an angle bar secured by one flange thereto, the projecting flanges of said bars and said base having cooperating projections and recesses to engage upon edgewise movement of said plates to hold said plates against lateral movement on said base, each of said plates having at one side adjacent its upper edge a second angle bar secured by one-flange thereto, said secondmentioned angle bars of said end plates being adapted to overlie the ends of said angle bars on the side plates, the adjacent ends of all of said second-mentioned angle bars having cooperating projections and recesses to engage upon edgewise movement of said end plates and hold all of said plates together, a top plate supported on the projecting flanges of said second-mentioned angle bars, and an outer wall including side and end plates arranged edgewise on said base in spaced relation to said core, said plates each having an angle bar secured by one flange thereto with its ends adapted to overlap the ends of the bars on adjacent plates and formed with cooperating projections and recesses to engage upon edgewise movement of said side plates to connect said plates. 7

3. A mold comp-rising a base, a former plate on the upper-side thereof having a continuous groove spaced inward from the sides and ends of said former plate, a wall surrounding said former plate in spaced relation to the edges thereof to form a peripheral depression between said wall and said former plat-e, and a sheet of metal arranged over said former plate, said groove and the bottom of said peripheral depression.
